It has been reported that various liquids confined in nano gaps has unique mechanical characteristics different from those in the bulk state. Specifically, the mobility of the liquid molecules is lowered due to the intermolecular interaction with the surface, and the non-Newtonian property such as the viscosity increase, solidification, and shear thinning of the liquid occurs in the nano gap, which is known as the nan-confinement effect. As for the nano-confinement effect, no theory has been constructed, prediction of the effect is difficult from macroscopic physical properties, and measurement method is not sufficiently established. This research aims to elucidate the mechanical properties (shear viscoelasticity) of lubricating oil cofined in the nano gap by establishing original measurement method.
